[0004] The two ends of the main truss in the above patent application are located on the same horizontal plane, so its stress is relatively simple, but in the present invention, an arc-shaped steel beam with a large height difference is set, and its two ends have a span internal tension, and its stress is complicated. If the method in the above patent application is adopted, it will not be able to meet its force requirements, and there is an urgent need for a large roof support that can meet its force requirements without changing the original structure of the roof support and without increasing the structural complexity of the roof support. Height difference curved roof support

Embodiment
[0045] see Figure 1-Figure 6 , as shown in the illustration, the arc-shaped roof support with large height difference includes an upper support 1, a lower support 2 and several arc-shaped steel beams 3. The upper support 1 and the lower support 2 extend along the same set direction and are arranged in parallel. , a number of arc-shaped steel beams 3 are arranged at intervals along the above-mentioned set direction and are respectively connected between the upper bracket 1 and the lower bracket 2 .
[0046] The upper bracket 1 includes a number of triangular brackets 11 which are pre-cast on the main body of the structure and arranged at intervals along the above-mentioned set direction. The arc-shaped steel beam 3 is also connected with a connecting support beam 12, and the connecting support beam 12 is also connected with a supplementary support. When the beam 13 and the arc-shaped steel beam 3 are in the working position: the connecting support beam 12 is connected to the u...

The invention discloses a method for installing an arc-shaped roof support with a large height difference, which comprises the following steps: respectively installing a slideway beam structure on an upper support and a lower support; Set the first limit block structure on the load-bearing beam structure; hoist the arc-shaped steel beam between the upper bracket and the lower bracket to form a sliding connection; slide the arc-shaped steel beam to the preset working position; The upper end of the shaped steel beam is butt welded with the upper bracket and the lower end of the arc steel beam is butt welded with the lower bracket; the slideway beam structure is removed from the upper bracket and the lower bracket respectively, and the load-bearing beam structure is removed from the arc The two ends of the steel girder are removed; the above-mentioned installation method can meet the stress performance of the curved roof bracket with large height difference, the installation is simple and convenient, and does not affect the original structure and shape of the curved roof bracket with large height difference. The utility model relates to an installation structure of a curved roof bracket with a large height difference.
Description
technical field [0001] The invention relates to a large height difference arc-shaped roof support, and in particular to a large-level difference arc-shaped roof support installation method and installation structure. Background technique [0002] With the vigorous development of my country's economic construction, large public buildings such as airports, convention centers, gymnasiums, auditoriums, etc. have been widely used. These buildings are generally long-span space steel structures, and the structural forms include grid frames, space analysis frames, etc. The on-site installation of steel structures can generally be divided into high-altitude bulk method, strip or block installation method, and high-altitude sliding method according to the comprehensive factors such as the force and structural characteristics of the analysis frame, site conditions, site construction technical conditions and equipment resources. , the overall hoisting method, the overall lifting method...
